Coffee milk was introduced to Rhode Island sometime in the early 1930s. It came about from creative diner and drugstore operators trying to attract new customers with creative drinks. One of these operators, who is lost to history, sweetened leftover coffee grounds with milk and sugar. This created a molasses-like extract that became popular. Coffee milk became a favorite among Rhode Islanders and created a demand for this coffee syrup. The demand was so great, that in 1993, it beat out Del's Lemonade as the official drink of Rhode Island.
